The contribution of two cations (Na+·H2O and H+) and an anion
(Cl−) were detected when the SWCNT electrode surface is negatively
and positively charged, respectively. The deconvolution of the global
EQCMresponse into distinct contributions (identification of ions, solvation
numbers and free solvent contributions) and the kinetics of
electroadsorption are the strong assets of the ac-electrogravimetry
